Dry land ski

ABSTRACT

Provided herein is a training device configured to allow a user to simulate all of the balancing and turning movements of downhill snow skiing or snowboarding on dry, downhill surfaces. The device is equipped with a braking system that allows the user to slow down the speed of travel when the moving direction changes from forward to sideways, thereby simulating the act of slowing down on a slope by turning a ski or snowboard. The braking effect is further enhanced when the ski or snowboard is tilted towards the uphill direction, further simulating the actual movements of skiing or snowboarding on snow. The braking system may include one or more mechanisms to amplify the force applied to the brake cables. An optional steering bar may be provided with handles that are positioned ahead of the bar to simulate the planting of ski poles prior to or during a turn.

BACKGROUND OF THE INVENTION

Field of the Invention

The invention relates generally to a training device and more particularly to a training device for use in acquiring balancing abilities, skills and techniques related to board-riding sports such as snowboarding and skiing.

Background Information

Board-riding sports require the individual to posture generally upright on a board's planar surface. The rider frequently adjusts his or her balance to remain upright on the board. The skill required to ride a snowboard is generally similar to riding other boards. In snowboarding, changing directions, itself, requires balance adjustments that alter the snowboard's direction of travel over the surface of the snow's terrain. The edges of the board displace surface snow as the board travels. The rider balances by applying pressure to the planar surface and edges of the board through the lower extremities.

Skiers and other sliding sport enthusiasts begin their sport without the ability to control their speed, and/or their direction of travel. This lack of control causes embarrassment, anxiety, and sometimes injury. Beginners frequently fall hard on the ground or slide out of control, often into people or obstacles. Most beginning skiers first learn to control their speed with a braking wedge maneuver, and later learn to control speed with turning.

One problem, however, that exists with the participation in many of these sports is that these activities must often be performed in locations under conditions that are not easily reproducible in other locations. Hence, one's ability to master certain skills related to the use of these devices is limited since weather and geographical constraints may limit the amount of time that one may devote to mastering these skills.

Accordingly, a need exists for a training device that simulates all of the balancing and turning movements of downhill snow skiing or snowboarding on dry, downhill surfaces.

SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE INVENTION

The present invention is based on the design of a training device configured to allow a user to simulate all of the balancing and turning movements of downhill snow skiing or snowboarding on dry, downhill surfaces. The device is equipped with a braking system that allows the user to slow down the speed of travel when the moving direction changes from forward to sideways, thereby simulating the act of slowing down on a slope by turning a ski or snowboard. The braking effect is further enhanced when the ski or snowboard is tilted towards the uphill direction, further simulating the actual movements of skiing or snowboarding on snow. An optional steering bar may be provided with handles that are positioned ahead of the bar to simulate the planting of ski poles prior to or during a turn.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Although any methods and materials similar or equivalent to those described herein can be used in the practice or testing of the invention, the preferred materials are now described.

Referring to FIGS. 1-5, the invention provides a training device 100 configured to allow a user to simulate all of the balancing and turning movements of downhill snow skiing or snowboarding on dry, downhill surfaces. The training device includes a footboard 14 having a top surface 50, bottom surface 56, front surface 52 and back surface 54. The footboard 14 may be made from any rigid material that can support the weight of a user. Exemplary materials from which the footboard may be formed include, but are not limited to, metal, plastic, fiberglass, and carbon fiber. In certain embodiments, the footboard 14 may be constructed from materials used in the production of modern skis and snowboards.

As shown in FIGS. 1, 2, 4, 5, 11, 12, 15, and 18, the footboard 14 includes a front hinge assembly 12 fixedly attached to the bottom surface 56 and adjacent to the front surface 52 thereof. The hinge assembly 12 hingedly connects the footboard 14 to a front neck 3 such that the footboard 14 may rotate about an axis A (FIG. 6). In certain embodiments, the hinge assembly 12 includes a means for preventing the footboard 14 from rotating beyond a certain point in either direction. For example, the hinge assembly 12 may be configured to prevent the footboard 14 from rotating beyond 30°, 45°, 60°, or 90° from rest position. In certain embodiments, the hinge assembly 12 may be adjustable such that a user may set the maximum allowable rotation of the footboard 14. As used herein, the term “rest position” refers to the position of a component of the training device when the training device is not being used and/or is in use and traveling in a straight line. Thus, when used in reference to the footboard 14, the “rest position” refers to a position wherein the footboard 14 has the surface upon which a user stands (i.e., the top surface 50) facing up Likewise, when used in reference to the front/rear wheels, the “rest position” refers to a position of the wheels wherein the training device will roll in a straight, forward direction.

The footboard 14 also includes a rear hinge assembly 22 fixedly attached to the bottom surface 56 and adjacent to the back surface 54 thereof. The rear hinge assembly 22 hingedly connects the footboard 14 to a rear neck 23 such that the footboard 14 may rotate about an axis A (FIG. 6). In various embodiments, the rear hinge assembly 22 may also include a means for preventing the footboard from rotating beyond a certain point in either direction, and may be user adjustable, as described above.

The front and rear necks (3, 23) of the training device 100 may be made from any rigid material known in the art. Exemplary materials from which the front and rear necks may be formed include, but are not limited to, metal, plastic, fiberglass, and carbon fiber. While the necks may be formed from the same material as that of the footboard, in certain embodiments, the necks are formed from different rigid materials. As shown in FIG. 2, the front neck 3 and rear neck 23 may be shaped to include one or more curves to accommodate the wheels of the training device 100. In certain embodiments, the necks are shaped into opposing “S” curves, where the bottom portion of each “S” curve serves as the point of attachment to the respective hinge assemblies (12, 22). Formed at the ends of the necks opposite to the attachment points to the hinge assemblies are holes, each configured to accommodate the stems of a front fork 7 and a rear fork 27, respectively, thereby forming front and rear pivot assemblies (4 a, 24 a).

The front fork 7 and rear fork 27 of the training device 100 may be made from any rigid material known in the art. Exemplary materials from which the footboard may be formed include, but are not limited to, metal, plastic, fiberglass, and carbon fiber. While the forks may be formed from the same material as any of the footboard 14, front neck 3, or rear neck 23, in certain embodiments, the forks are formed from a different rigid materials, such as aluminum or steel. In certain embodiments, the lower arms of each fork may be replaced with and/or integrated with a shock absorbing system (not shown) to accommodate rough surfaces.

Each fork (7, 27) may be shaped to accommodate an axle (not shown) around which one or more wheels (10, 20) rotate. The wheels (10, 20) may be solid or hollow (with an inner tube), and may be formed from materials known in the art. Exemplary materials from which the wheels may be formed include, but are not limited to, rubber and plastic. While a single wheel may be mounted at each end (front/rear) of the training device 100, in various embodiments, there may be mounted two concentric wheels at each end for added stability during use.

The training device 100 further includes a braking system 60. As shown in FIGS. 3, 16A, and 16B, mounted at a central position of each fork (7, 27) is a brake scissor assembly (8, 28), each of which includes a first brake arm (8 a, 28 a) and a second brake arm (8 b, 28 b). Disposed at the distal ends of each brake arm is a brake shoe 9 configured to inhibit rotation of a wheel through frictional contact therewith. Fixedly attached to the proximal ends of each brake arm is a first end of a brake cable 6 b. The brake cables used in the training device 100 may be formed from materials known to those of skill in the art.

The braking system 60 includes two front brake cables 6 b, one for each side (right/left) of the device. Hereinafter, the disposition of a single front brake cable 6 b will be described, but it should be understood that the following description applies to both the left and right side simultaneously.

The front brake cable 6 b is slidably disposed within a rigid brake tube 6 a that is mounted to either side of the front fork 7. The rigid tube 6 a terminates at the top portion of the front fork 7 adjacent to the front pivot assembly 4 a. As shown in FIGS. 9 and 10, the front brake cable 6 b exits the rigid tube 6 a, passes through a rotating tube 4 b fixedly mounted to the front pivot assembly 4 a, and enters a flexible tube 6 c mounted adjacent to the front neck 3. Flexible tube 6 c terminates at front extruded guide tube 15 and is extendable along its length such that rotation of the front wheel in either direction causes the flexible tube 6 c opposite to the direction of rotation to flex. Because the length of brake cable 6 b is fixed, the flexing of flexible tube 6 c increases tension of the brake cable 6 b contained therein, resulting in an overall increase in tension along the entire brake cable 6 b and application of the respective brake assembly. Thus, when the portion of brake cable 6 b that is inside flexible tube 6 c increases in length as the result of the turning of the wheels, the length of the portion of brake cable 6 b between the lower end of rigid tube 6 a and the first end of brake cable 6 b at the brake arm is shortened, resulting in the application of the respective brake arm(s), which causes the brake shoe(s) 9 to contact the wheels and slow the device down. The brake cable 6 b then enters the front neck 3 through front extruded guide tubes 15 at a location proximal to the front pivot assembly 4 a, and exits from a location proximal to the front surface 52 of the footboard 14. Within the front neck 3, the brake cable 6 b may optionally be slidably disposed within a protective tube (not shown) to prevent deterioration thereof. The second end of the front brake cable 6 b may optionally be slidably disposed within a protective tube (not shown) to protect the brake cable 6 b from the environment, and is fixedly attached to the front surface 52 of the footboard 14.

The training device 100 further includes two rear brake cables 26 b, one for each side (right/left) of the device. Hereinafter, the disposition of a single rear brake cable 26 b will be described, but it should be understood that the following description applies to both the left and right side simultaneously.

The rear brake cable 26 b is slidably disposed within a rigid brake tube 26 a that is mounted to either side of the rear fork 27. The rigid tube 26 a terminates at the top portion of the rear fork 27 adjacent to the rear pivot assembly 24 a. As shown in FIGS. 16-18, the rear brake cable 26 b exits the rigid tube 26 a, passes through a rotating tube 24 b fixedly mounted to the rear pivot assembly 24 a, and enters a flexible tube 26 c, which is extendable along its length and mounted within the rear neck 23 such that the ends of the flexible tube 26 c protrude from the rear neck 23 through rear extruded guide tubes 25 disposed at a location proximal to the rear pivot assembly 24 a, and from a location proximal to the rear surface 54 of the footboard 14. The second end of the rear brake cable 26 b may optionally be slidably disposed within a protective tube (not shown) to protect the brake cable 26 b from the environment, and is fixedly attached to the rear surface 54 of the footboard 14. Additionally, flexible tubes 26 c cross-over from left to right, and vice versa, at a point proximal to the rear pivot assembly 24 a such that the opposite side rear brake arm, as compared to the front brake arm, is actuated as a result of the turning of the rear wheel 20.

Disposed at one or more of the ends of the front brake cables 6 b and rear brake cables 26 b may be an adjusting barrel (6 d, 26 d) that connects the respective brake cables to the brake scissor arms (8 a, 8 b, 28 a, 28 b) and allows for user adjustment of brake cable tension within the braking system 60. Alternatively or in addition thereto, the training device 100 may include adjusting barrels (6 d, 26 d) at the second ends of the brake cables (6 b, 26 b) to adjustably attach the brake cables (6 b, 26 b) to the front surface 52 and the rear surface 54 of the footboard 14, respectively. As shown in FIG. 10, the brake system 60 may further include one or more front cable stoppers 17 mounted to the front brake cables 6 b within the front neck 3 and configured to prevent the front brake cables 6 b from moving towards the wheels, thereby ensuring that the appropriate brake arm is actuated as a result of the turning of the wheels. Likewise, as shown in FIG. 16B, the brake system 60 may further include one or more rear cable stoppers 18 mounted to the rear brake cables 26 b within the rear neck 23 and configured to allow the rear brake cables 26 b to move only towards the footboard 14, thereby ensuring that the appropriate brake arm is actuated as a result of the turning of the wheels.

The training device 100 may further include one or more torsion springs (5 a, 5 b) mounted at the pivot assemblies (4 a, 24 a), and configured to return the front/rear wheels to their respective rest positions. In various embodiments, the training device 100 may include only a front torsion spring 5 a mounted at the front pivot assembly 4 a, or only a rear torsion spring 5 b mounted at the rear pivot assembly 24 a. In various embodiments, the training device 100 may include both a front torsion spring 5 a mounted at the front pivot assembly 4 a, and a rear torsion spring 5 b mounted at the rear pivot assembly 24 a.

The training device may further include a handle bar 2 fixedly attached to the front fork 7 and configured to allow a user to simulate the planting of a ski pole prior to and during a turn, while turning the front wheels 10. The handle bar 2 may include a first and second hand grip 1. The handle bar 2 may be detachable from the front fork 7 for advanced training. Thus, when a user turns the handle bar 2 to the left the front wheels turn left and, as a result of the frictional movement of the training device, the rear wheels 20 also turn to the left, thereby simulating a sideways slide on skis. However, the front and back wheels (10, 20) will be pulled by gravity to rotate at equal angles to simulate a carving action or skidding of skis during a turn (see, e.g., FIGS. 7 and 8).

As both the front and the rear wheels (10, 20) turn sideways in the same direction, and the front and rear pivot assemblies (4 a, 24 a) are turning at the same angle, the flexible brake cable tubes (6 c, 26 c) on the “uphill side” (i.e., the opposite side of the direction that the wheels are turning toward) of the footboard 14 will flex, thereby accommodating more brake cable (6 b, 26 b). Meanwhile, the rigid brake cable tubes (6 a, 26 a) on the same side, will accommodate the same length of brake cable independent of the wheel direction. Because the brake cable length is fixed between the cable stopper (17, 18) and the point of attachment to the respective brake scissor arms (8 a, 8 b, 28 a, 28 b), the turning of the wheels will cause the brake shoes to gently touch the wheel rims and slow down the wheels (see, e.g., FIGS. 12 and 14).

The user may apply further braking force by tilting the footboard towards the uphill direction. In this case, the tilting of the footboard 14 pulls on the uphill side brake cables (6 b, 26 b) further reducing the total length of flexible tube 26 c beyond the cable stopper (17, 18), and increasing pressure applied to the brake shoes against wheels (10, 20).

Accordingly, when a user shifts its weight left, the front and rear wheels (10, 20) turn right, thereby urging the second front and second rear braking arms to respectively contact the front and rear wheels (10, 20). Likewise, when a user shifts its weight right, the front and rear wheels turn left, thereby urging the first front and first rear braking arms to respectively contact the front and rear wheels (10, 20).

The training device 100 may further include an electric motor 11 fixedly attached to the front fork 7 and configured to provide rotational power to the front wheels 10. The electric motor 11 may be connected to an electric source such as, but not limited to, a rechargeable battery pack or a solar array. The electric motor 11 may further serve as a generator to charge the rechargeable battery pack while the training device is moving by gravitational power. The electric motor 11 may further include a user-selectable on-off switch (not shown), as well as an integrated controller (not shown) to control the switching between motor and generator as conditions vary. Thus, a user may utilize the rotational power of the motor 11 for added downhill speed and/or to facilitate traveling uphill in preparation for another downhill training session.

FIGS. 19A-19C are perspective views of various exemplary embodiments of the training device 100. FIG. 19A shows the training device 100 as has been described, with foot positions 16 referencing a monoski configuration. FIG. 19C shows the training device 300 with the handlebar 2 having been removed and including a single front wheel 10 and single rear wheel 20. As shown in FIG. 19C, foot positions 16 on footboard 14 reference a snowboard configuration.

Referring now to FIG. 19B, the invention further provides a training system 200. The training system 200 includes a first and a second training device configured to simulate independent skis. Thus, the foot positions 16 on footboard 14 are shown facing the forward direction of the system. Each training device of the training system 200 may include the features described above with reference to the training device 100, and may further include one handlebar 2 (not shown) per training device to simulate use of ski poles.

Referring now to FIGS. 20-28, another exemplary embodiment of the training device 400 is shown, wherein elements consistent with the previous embodiments are given the same element numbers. In this embodiment of the training device, there is provided a footboard assembly 31 that includes a first footboard 30 and a second footboard 32, each having a top surface 34, bottom surface (not shown), front surface 36 and back surface 38. The first and second footboards (30, 32) may be made from any rigid material that can support the weight of a user. Exemplary materials from which the footboard may be formed include, but are not limited to, metal, plastic, fiberglass, and carbon fiber. In certain embodiments, the footboards (30, 32) may be constructed from materials used in the production of modern skis and snowboards.

As shown in FIG. 22, the footboards (30, 32) may each include a front hinge assembly 40 fixedly attached to the front surface 36 of the footboard (30, 32) and a rear hinge assembly 42 fixedly attached to the rear surface 38 of the footboard (30, 32). Each of the front hinge assembly 40 and rear hinge assembly 42 hingedly connects the respective footboard (30, 32) to a front crossbar 44 and a rear crossbar 46, which are fixedly attached to one another by a frame bar 48. In certain embodiments, each of the hinge assemblies (40, 42) may include a means for preventing the respective footboards (30, 32) from rotating beyond a certain point in either direction. For example, the hinge assemblies (40, 42) may be configured to prevent the footboards (30, 32) from rotating beyond 30°, 45°, 60°, or 90° from rest position. In certain embodiments, the hinge assemblies (40, 42) may be adjustable such that a user may set the maximum allowable rotation of the footboards (30, 32).

The front and rear crossbars (44, 46) and the frame bar 48 may be made from any rigid material known in the art. Exemplary materials from which the crossbars may be formed include, but are not limited to, metal, plastic, fiberglass, and carbon fiber. In various embodiments the front and rear crossbars (44, 46) and the frame bar 48 are made from the same material, but the invention is not limited thereto, as these components may be independently formed from different materials.

The front and rear crossbars (44, 46) are each fixedly attached to a front neck 3 and a rear neck 23, as was described with reference to the previous exemplary embodiments. The front and rear necks (3, 23) of the training device 400 may be made from any rigid material known in the art. While the necks may be formed from the same material as that of the footboard, in certain embodiments, the necks are formed from different rigid materials. As shown in FIG. 21, the front neck 3 of the training device 400 is sized to accommodate a front wheel 10 that is larger than the rear wheel 20. In addition, the training device 400 includes a seat 70 fixedly attached to the front neck 3, thereby allowing a user to be seated while riding, as would be done with a conventional bicycle. Thus, the training device 400 may further include a first foot pedal 62 and second foot pedal 64, each fixedly mounted to opposite ends of an axle of rotation of the front wheel 10. As in a conventional bicycle, the foot pedals (62, 64) may be mounted to the axle 68 of the front wheel 10 by means of a pair of crank arms 66, which are offset from each other by 180° with respect to the direction of rotation of the wheel 10.

Consistent with the previous exemplary embodiments, the training device 400 includes a first braking system 60, which is described above and therefore will not be repeated here. As shown in FIGS. 22, 23, and 26, the front brake cable 6 b exits the front neck 3 at a location proximal to the front pivot assemblies 40 of the footboard assembly 31. Each front brake cable 6 b is then slidably disposed within a protective tube 94 and passes through the front crossbar 44 for fixed attachment to the front surfaces 36 of each footboard (30, 32). Likewise, as shown in FIGS. 22, 27, and 28, each rear brake cable 26 b exits the rear neck 23 at a location proximal to the rear hinge assembly 42 of the footboard assembly 31. Each rear brake cable 26 b is then slidably disposed within a protective tube 96 and passes through the rear crossbar 46 for fixed attachment to the back surfaces of each footboard (30, 32). However, in this embodiment, flexible tubes 26 c do not cross-over from left to right, but rather are located such that the rear brake arm on the same side as the front brake arm is actuated as a result of the turning of the rear wheel 20.

The training device 400 may further include a second braking system 80. As shown in FIGS. 25-28, the second braking system 80 includes a second brake scissor assembly (82, 84), each of which including a first brake arm (82 a, 84 a) and a second brake arm (82 b, 84 b). Disposed at the distal ends of each brake arm is a brake shoe 9 configured to inhibit rotation of a wheel through frictional contact therewith. Fixedly attached to the proximal ends of each brake arm of the second braking system 80 is a first end of a brake cable. As with the previous exemplary embodiments, the brake cables used in the training device 400 may be formed from materials known to those of skill in the art.

Unlike the first braking system 60, the second braking system 80 includes a single front brake cable 83 and a single rear brake cable 88. Hereinafter, the disposition of the front brake cable 83 of the second braking system 80 will be described.

As shown in FIGS. 23 and 24, the front brake cable 83 is slidably disposed within a front flexible brake tube 90 that is mounted to a side of the front fork 7. The front flexible tube 90 is disposed parallel to the handlebar 2 that is fixedly attached to the front fork 7, and terminates at the top of the handlebar 2 at a hand control 85.

As shown in FIGS. 27 and 28, the rear brake cable 88 is slidably disposed within a rear flexible brake tube 86 that is mounted to the handlebar 2 that is fixedly attached to the front fork 7, with a first end terminating at the top of the handlebar 2 at a hand control 85. The rear flexible tube 86 is disposed to run under the front neck 3, the front crossbar 44, the frame bar 48, the rear crossbar 46, and the rear neck 23. The second end of the rear brake tube 86 terminates proximal to the second rear scissor assembly 84, thereby allowing the rear brake cable 88 to be fixedly attached thereto.

Disposed at one or more of the ends of the front brake cable 83 and rear brake cable 88 may be an adjusting barrel (not shown) that connects the respective brake cables to the brake scissor arms (82 a, 82 b, 84 a, 84 b) and allows for user adjustment of brake cable tension within the second braking system 80. Alternatively or in addition thereto, the training device 400 may include adjusting barrels (not shown) at the second ends of the brake cables (83, 88) to adjustably attach the brake cables to each of the hand controls 85, respectively.

In certain embodiments, the braking system 60 of each of the above-described training devices (100, 300, 400) may have a different configuration from the one described above. As shown in FIG. 29, mounted at a central position of the front fork 7 is a brake scissor assembly 8, which includes a first brake arm 8 a and a second brake arm 8 b. Disposed at the distal ends of each brake arm is a brake shoe 9 configured to inhibit rotation of a wheel through frictional contact therewith. Fixedly attached to the proximal ends of each brake arm is a first end of a brake cable. The brake cables used in the training device 100 may be formed from materials known to those of skill in the art. It should be understood that for purposes of explanation, the alternative braking system is described with reference to the front brake system only. However, the alternative braking system is applicable to and therefore contemplated for use as rear brake system and/or both the front and the rear brake system.

In these embodiments, the front brake system 60 includes a single front brake cable 6 b (to be referred to as the primary brake cable 6 b), a first end of which being fixedly attached to each brake arm (8 a, 8 b) for simultaneous actuation thereof. The primary brake cable 6 b is slidably disposed within a protective tube 98 that is fixedly attached to the front fork 7. The second end of the primary brake cable 6 b exits the protective tube 98 and is fixedly attached to a pair of secondary front brake cables 6 e, one for each side (right/left) of the device.

As described above with respect to the front brake system 60 of training device 100, each front secondary brake cables 6 e passes through a rotating tube 4 b fixedly mounted to the front pivot assembly 4 a, and enters a flexible tube 6 c, which is extendable along its length and mounted adjacent to the front neck 3 such that rotation of the front wheel in either direction causes the flexible tube 6 c opposite to the direction of rotation to flex and increase tension of the brake cable 6 b contained therein. The remaining features of the front brake system are identical to those described above with regard to training device 100, and therefore will not be described here for brevity.

In certain embodiments, the braking system 60 of each of the above-described training devices (100, 300, 400) may have a different configuration from the one described above. As shown in FIGS. 30A and 30B, the hinge assemblies (12, 22) may include a main shaft 110 that extends from the front neck 3 to the rear neck 23, and is configured to be fixedly attached to footboard 14 by means of front and rear clamps 112. The ends of main shaft 110 protrude into each of front neck 3 and rear neck 23 and may terminate in an annular socket 114 formed in an inner surface of a wall of the front neck 3 and rear neck 23. In certain embodiments, annular socket 114 may include a rotational element, such as a roller bearing (not shown) to minimize friction during rotation of the main shaft 110. Disposed on the main shaft 110 at positions proximal to the ends thereof may be a drum 116 configured to rotate within the front and rear necks (3, 23) in accordance with the rotation of the main shaft 110.

As described above with reference to other embodiments of the training device (100, 300, 400), the front brake system 60 includes two front brake cables 6 b, one for each side (right/left) of the device. To the extent that the features of the front and rear brake system are identical to those described above with regard to training devices 100, 300, and 400, only the differences will be described here for brevity.

The left and right brake cables 6 b enter the front neck 3 at a location proximal to the front pivot assembly 4 a and are fixedly attached to the drum 116 at positions that are essentially 180° apart from each other. Thus, when a user causes the footboard 14 to rotate in either direction, the drum 116 concentrically rotates in the same direction and applies tension to the respective brake cable 6 b. Without being bound by theory, because the diameter of the drum 116 is greater than that of the main shaft 110, the tension applied to the brake cable 6 b is amplified as compared to the tension that is applied in a device (100, 300, 400) having a brake system 60 without the drum 116.

It should be understood that for purposes of explanation, this alternative braking system including the amplifying drum 116 is described as including a drum 116 disposed within each of the front and rear necks (3, 23). However, in various embodiments, the braking system 60 may include a single drum 116 disposed in either of the front neck 3 or the rear neck 23. Thus, the alternative braking system is applicable to and therefore contemplated for amplifying tension applied to the front brake cables only, the rear brake cables only, or both the front and the rear brake cables.

In certain embodiments, the braking system 60 of each of the above-described training devices (100, 300, 400) may have a different configuration from those described above. As discussed above with reference to FIGS. 30A and 30B, the hinge assemblies (12, 22) may include a main shaft 110 that extends from the front neck 3 to the rear neck 23, and is configured to be fixedly attached to footboard 14 by means of front and rear clamps 112. As shown in FIGS. 31A and 31B, each of the front and rear necks (3, 23) may include a gearbox (150, 250). Disposed on the main shaft 110 at positions proximal to the ends thereof may be a primary gear 122 configured to rotate within the gearbox (150, 250) of each of the front and rear necks (3, 23) in accordance with the rotation of the main shaft 110. Also disposed within the gearbox (150, 250) are a plurality of secondary gears 124, each configured to rotate in accordance with contact with the primary gear 122. While the exemplary embodiment shown in FIGS. 31A and 31B show that one primary gear 122 and three secondary gears 124 are provided in the front and rear necks, it should be understood that any number of secondary gears 124 are contemplated for use in the gearbox (150, 250) to amplify the tension applied to the brake cables 6 b.

As shown in FIG. 31A, primary gear 122 is in rotational engagement with a first secondary gear 124, which is fixedly attached at a position proximal to a proximal end of a gear shaft 126. Thus, gear shaft 126 is disposed within the gearbox (150, 250) in close proximity to main shaft 110 to enable engagement of the first secondary gear 124 with primary gear 122. While gear shaft 126 is shown as being disposed above main shaft 110, it should be understood that gear shaft 126 may be mounted in any configuration (e.g., below or laterally in any direction) so long as the primary gear 122 and the secondary gear 124 are in contact with each other. Gear shaft 126 protrudes through inner wall 120 with the proximal end terminating in an annular socket 114 formed in an inner surface of a wall of the front neck 3 and rear neck 23, and a distal end terminating in an annular socket 114 of a partial wall 128 disposed within the gearbox (150, 250).

Disposed at a position proximal to the distal end of the gear shaft 126 may be a second secondary gear 124 configured to rotate in accordance with rotation of the gear shaft 126. The second secondary gear 124 may be in rotational engagement with a third secondary gear 124, which is fixedly attached to an output shaft 130 at a position proximal to a proximal end thereof. Output shaft 130 is disposed within the gearbox (150, 250) in close proximity to the gear shaft 126, with ends terminating in annular sockets 114 formed in the inner wall 120 and an inner surface of the front and rear necks (3, 23). Disposed at a position proximal to the distal end of the output shaft 130 is a drum 116 configured to rotate with rotation of the output shaft 130. In certain embodiments, any one or more of annular sockets 114 may include a rotational element, such as a roller bearing (not shown) to minimize friction during rotation of the main shaft 110, gear shaft 126, and/or the output shaft 130.

As described above with reference to other embodiments of the training device (100, 300, 400), the front brake system 60 includes two front brake cables 6 b, one for each side (right/left) of the device. To the extent that the features of the front and rear brake system are identical to those described above with regard to training devices 100, 300, and 400, only the differences will be described here for brevity.

The left and right brake cables 6 b enter the front neck 3 at a location proximal to the front pivot assembly 4 a and are fixedly attached to the drum 116 at positions that are essentially 180° apart from each other. Thus, when a user causes the footboard 14 to rotate in either direction, primary gear 122 rotates, thereby causing each of secondary gears 124 to rotate, which in turn, causes the drum 116 to concentrically rotate and apply tension to the respective brake cable 6 b. The gear ratios of the gearbox (150, 250) may be selected in accordance with the desired amplification of rotational force applied to the respective brake cables 6 b as a result of the tilting of the footboard 14 by a user. As such, the resulting tension applied to the brake cable 6 b is amplified as compared to the tension that is applied in a device (100, 300, 400) having a brake system 60 without a gearbox (150, 250).

It should be understood that for purposes of explanation, this alternative braking system including the gearbox (150, 250) for amplifying the rotational force applied to the drum 116 is described as including a gearbox (150, 250) within each of the front and rear necks (3, 23). However, in various embodiments, the braking system 60 may include any combination of gearbox (150, 250), drum 116 without gearbox (150, 250), or non-amplified application of brakes within the front and/or rear necks (3, 23) of the training device (100, 300, 400). Thus, the alternative braking system is applicable to and therefore contemplated for amplifying tension applied to the front brake cables only, to the rear brake cables only, or to both the front and the rear brake cables.
